Introduction Graphene is a highly useful material, made solely of monolayered carbon atoms patterning a monoatomic honeycomb. Particularly, the automatic operation of many washing sequences saves labor time, and the reuse of the washing solvent spares a large volume of chemically deleterious solvents. Soxhlet rinsing is favored environmentally and economically. Finally, we discuss the benefits involved in the suggested rinsing method and compare its profitability with traditional methods. Moreover, we test the electrochemical performances of reduced GO (rGO), the main final product of graphite-oxide. The quality of the produced GO is evaluated by Raman spectroscopy, X-Ray diffraction (XRD), inductively coupled plasma (ICP), elemental analysis, and electron microscopy. ![]() Since only the vapor of the solvent is used for washing, Soxhlet rinsing offers reuse of the same solvent for many automatic subsequent cycles, leading to considerable solvent savings, reducing pollutants and work time, and ensuring safer production. This study reveals an alternative method to rinse graphite-oxide using a Soxhlet extractor. Traditionally, the rinsing involves filtration or centrifugation both processes are extremely time-consuming, expensive, unsafe, and produce environmentally hazardous liquid waste in large volume. Proper rinsing is essential to obtain processable and applicable graphite-oxide. The procedure for converting graphite into GO includes two steps: oxidation and subsequent rinsing. Compared with the general soaking method, it has the advantages of small solvent dosage, high efficiency and complete extraction.Graphite-oxide (GO) is a valuable compound produced by the chemical oxidation of graphite. The advantage of Soxhlet extraction is that it can be extracted multiple times. Once the level of solvent reaches the siphon it pours back into the flask and the cycle begins again. The condensate then drips into the reservoir containing the thimble. Due to heat the solvent in the bottom flask vaporizes into the condenser. The solvent is heated using heating source like isomantle and will begin to evaporate, moving through the apparatus to the condenser. ![]() The sample material is packed in filter paper and placed in the thimble which is placed inside the Soxhlet extractor. In this method, sample needs to be crushed, using a pestle and mortar, to provide a greater surface area. The soxhlet extractor setup consists of a round bottom flask, siphon tube, distillation path, expansion adapter, condenser, cooling water inlet, cooling water outlet, heat source and thimble. A wide variety of solvents like dichloromethane (DCM), pure or mixed with acetone or hexane, and acetone–hexane mixtures can be used. It has been used for a wide range of samples like soils, sediments, and animal and plant tissues. Soxhlet extraction is widely used for many types of solid samples, especially biological and environmental samples. The soxhlet extractor uses the solvent reflux and siphon principle to continuously extract the solid matter by pure solvent, which saves the solvent extraction efficiency and high efficiency. In the laboratory, soxhlet extractor is used for extraction. ![]() A Soxhlet extractor is a piece of laboratory apparatus designed in 1879 by Franz von Soxhlet.
